Cloud9: Updating Go and getting Buffalo setup with Postgres

Jul 18, 2020 - 2 minutes

When you setup your cloud9 IDE for the first time, it comes pre-installed with go1.9 - if you’d like to update to the latest (as of this writing), just run the following commands:

1wget https://golang.org/dl/go1.14.6.linux-amd64.tar.gz
2sudo tar -C /usr/local -xzf ./go1.14.6.linux-amd64.tar.gz
3mv /usr/bin/go /usr/bin/go-old # move the old binary

Edit your .bashrc file so your $PATH has the new location:

1export PATH=$PATH:$HOME/.local/bin:$HOME/bin:/usr/local/go/bin

Source the file again so your settings are reloaded:

1source ~/.bashrc

And now go version should show 1.14.6

Now lets install Buffalo with gofish:

1curl -fsSL https://raw.githubusercontent.com/fishworks/gofish/master/scripts/install.sh | bash
2gofish init
3gofish install buffalo
4buffalo version # should say 0.16.12 or whatever latest is

And finally let’s setup postgres:

 1sudo sh -c 'echo "deb http://apt.postgresql.org/pub/repos/apt $(lsb_release -cs)-pgdg main" > /etc/apt/sources.list.d/pgdg.list'
 2wget --quiet -O - https://www.postgresql.org/media/keys/ACCC4CF8.asc | sudo apt-key add -
 3sudo apt-get update
 4sudo apt-get install postgresql-12
 5sudo su - postgres 
 6psql
 7postgres=# create role ubuntu with superuser createdb login password 'ubuntu'; 
 8postgres=# create database ubuntu;
 9postgres=# exit
10exit

You should now be to execute psql from your regular user.

Let’s create our demo buffalo app:

1buffalo new demo
2cd demo

Edit your database.yml to look like this for development:

1---
2development:
3  url: {{envOr "DEV_DATABASE_URL" "postgres://ubuntu:ubuntu@/demo_development"}}

Then you can create and migrate your database:

1buffalo db create && buffalo db migrate

Now just run buffalo dev in your Cloud9 terminal and you can preview your application! (Cloud9 already sets the PORT env var).

And then you realize that auto-complete support doesn’t work with a small little

This feature is in an experimental state for this language. It is not fully implemented and is not documented or supported.

on the AWS product page, and go back to IntelliJ.
